Hey, I don't really know about the installation because I never ended up with it on my car, but I have an invader kit for sale. Its still in the box and hasn't been touched. I will sell it for $425 plus shipping. If you look around, that's about the cheapest you'll find. I totaled my car a week after i bought the kit (sucky deal, let me tell you). If you are interested, email me
